On Tuesday, Floyd Mayweather and Conor McGregor were promoting their upcoming fight at a press conference at Staples Center, when Floyd began shadow boxing and showing what he was going to do to McGregor in August.

Conor McGregor took that opportunity to yell out, ‘Dance for me, boy.’ That had social media buzzing for hours as referring to a black man as “boy” in America has an extremely negative history that goes all the way back to slavery.
